Made for Northern Europe, flown in Malaya

Bristol Brigand, developed from the Bristol Buckingham, was a nice-looking aircraft and easy to fly. 

“The Brigand was pleasant to fly, having nicely balanced flying controls and a wide range of power in the two Bristol Centaurus engines. These features made the aircraft splendid for formation flying, which was important to our method of operation. The aircraft also had sufficient range to reach targets all over Malaya from the Squadron's new base at Tengah, on Singapore Island.” – Squadron Leader A.C. Blythe

However, climate differences between factories in England and operations in Malaya brought unexpected, often fatal, problems.

“Problems with the Brigand became apparent during operations in Malaya, with undercarriages failing to lower. This was traced to rubber seals in the hydraulic jacks deteriorating in the hot, humid climate.[3] Just as this problem was being resolved another problem arose, more serious because it led to fatalities: a propensity for aircraft damage and loss during strafing runs employing the four 20 mm cannon. An accumulation of gases in the long cannon blast tubes, which ran under the cockpit, was igniting through use of high-explosive shells. This in turn severed hydraulic lines, which would burn. This was cured by drastically reducing ammunition loads and using only ball rounds.[4] The Brigand also had a tendency to shed a propeller blade, leading to complete propeller failure; this in turn would lead to the engine being wrenched off the wing and an inevitable crash. The problem was found to be caused by corrosion in the propeller locking rings. More frequent maintenance helped alleviate this problem.”

“As the Brigand became subject to more restrictions both unit commanders had serious doubts about the continued use of the aircraft.”

But, “It was decided to continue operating them, since as long as thorough maintenance was carried out it was felt that nothing else could go wrong. Another design flaw arose in the leather bellows used to deploy the air brakes during dives. In the tropical climate, the leather would rot, causing the brakes to fail. This led to Brigands losing wings in dives due to excessive airspeed or rotation as only one brake deployed. When this problem was discovered the air brakes of all Brigands were wired shut, decreasing the aircraft's dive bombing capabilities.

So, a pilot returning from a successful strafing of Communist guerrillas might not be able to get his landing gear down. Or, perhaps on a strafing run, gases accumulated beneath the cockpit exploded, which could cause the aircraft to lose flight characteristics.

Possibly losing propeller or failure of dive brakes …

A nice-looking aircraft, and had there been a Communist guerrilla outbreak nearer the English climate, the Brigand would be a better-remembered airplane.
